Abstract
A capacitive-type pressure sensor comprising a glass plate having an electrode formed thereon. A diaphragm is formed from a semiconductor material and bonded to the glass substrate to define an enclosed cavity containing at least a portion of the electrode, to thereby define a capacitive element, through which, in use, an electrical signal may be passed to determine a capacitance thereof which is indicative of the pressure to be determined.
